Definitions

• the present invention relates to a novel use of a nutraceutical composition for animals, especially pigs, comprising as active ingredient benzoic acid or derivatives thereof.
• derivatives of benzoic acid which can give rise to benzoic acid in vivo are alkali metal-alkaline earth metal- and ammonium benzoates.
• nutraceutical denotes an usefulness in both the nutritional and pharmaceutical field of application.
• nutraceutical compositions can find use as a complete animal feed (diet), as supplement to animal feed, and as pharmaceutical formulations for enteral or parenteral application which may be solid formulations, or liquid formulations.
• animal feed compositions comprising benzoic acid or salts thereof can be used to minimize the emission of odoriferous ammonia from organic wastes, especially animal excrements and manure. It is further known that the addition of benzoic acid to the diet of weaner piglets improves the zootechnical performance of the animals.
• estradiol benzoate is useful for increasing bone resistance and mineralization in rats.
• benzoic acid and salts thereof have the advantage of being able to improve bone strength in animals, more precisely being able to increase bone resistance and mineralization, which has a significant effect to the general health status of the animal.
• bone resistance denotes the maximal force in measured in Newton (N) necessary to break the bone determined by a compression machine.
• bone mineralization denotes the percentage of ash after incineration of the bone compared to the dried bone matter (DM). Dry matter is defined as the weight of the bone sample after 24 hour in a drying oven compared to the initial weight of the sample.
• the present invention relates to the use of benzoic acid or a derivative of benzoic acid capable of giving rise to free benzoic acid in vivo in the manufacture of a neutraceutical composition for increasing bone resistance and mineralization in animals, especially pigs.
• Benzoic acid or a derivative thereof capable of giving rise to benzoic acid in vivo is administrated to the animals as a component of a nutraceutical composition which is conventionally fed to animals.
• benzoic acid or said derivative may be suitably administered to the animals as a component of the animal feed or in their drinking water.
• the amount of benzoic acid or a derivative thereof capable of giving rise to benzoic acid in vivo f administered to the animal is in the range from 0.001 - 5% based on the total weight of each feed fed to the animal. This amount may, however, be higher if the function of benzoic acid or said derivative is also to control the pH of the animal excreta fed on such a diet in order to suppress the emission of ammonia from the excreta. Such higher amounts are suitably limited to a maximum of about 10% based on the total animal feed composition.
• the benzoic acid or derivative thereof capable of giving rise to benzoic acid in vivo is used in an amount sufficient to provide a daily dosage of 200 mg per kg body weight to about 600 mg per kg body weight of the subject to which it is to be administered.
• the use according to the invention achieves in the animal the following bone strength parameters: a bone resistance of at least 500 N measured with metacarpal bone and/or a bone mineralization of at least 60% of ash compared to the dried bone matter (DM).
• the feed comprises benzoic acid in an amount sufficient to achieve in the animal the following bone strength parameters: a bone resistance of at least 550 N, preferably 590 to 650 N measured with metacarpal bone.
• Table 1 A typical formulation for an animal feed composition is shown in Table 1 below in which all the amounts shown in % by weight were fed to pigs: Table 1 Ingredients % Meat meal (58% Crude protein) 3.20 Molasses 5.00 Wheat 5.90 Soybean meal (45% crude protein) 15.10 Tapioca (66% starch) 35.50 Wheat middlings 15.00 Animal fat 3.30 Limestone 0.74 Lysine hydrochloride (98%) 0.06 Vitamin premix 0.50 Trace minerals 0.50 Sunflower meal 12.20 Amonium chloride 2.00 Amonium benzoate 1.00
• benzoic acid or a derivative thereof capable of giving rise to benzoic acid in vivo may be used in combination with conventional ingredients present in an animal feed composition (diet) such as calcium carbonates, elelctrolytes such as ammonium chloride, proteins such as soya bean meal, wheat, starch, sunflower meal, corn, meat and bone meal, amino acids, animal fat, vitamins and trace minerals.
• Diet animal feed composition
• the ratio of the electrolyte to the benzoic acid or said derivative is suitably in the range from 0.5 : 1 to 5 : 1 w/w, preferably from 1.5 : 1 to 3 . 1 w/w.
• Benzoic acid or a derivative thereof capable of giving rise to benzoic acid in vivo is particularly effective to improve the digestibility of proteins and the assimilation of amino acids and nitrogen in animals such as poultry, pigs or cattle, especially pigs.
• Example 2 shows the effects of benzoic acid on the ileal apparent digestibility of nitrogen, energy and amino acids in the ileo-rectal anastomosed piglets
• Sixty-four Large-White x Landrace x Piétrain weaner piglets having an initial body weight of 8.5 ⁇ 1.11 kg were used.
• the animals were allocated into two equal groups (A1 and B1) and housed in cages in sub-groups of 6 animals each in an environmentally controlled room. Each cage had a plastic-coated welded wire floor and was equipped with 2 water nipples and 2 stainless-steel feeders. Room temperature was initially 27°C and was lowered weekly by about 2°C until 21-22°C.
• the Environment humidity percentage throughout the experiment was 50 %.
• the animals were fed the basal diet (group A1) or the diet A with addition of 0.5 % of benzoic acid (VevoVitall®, DSM Nutritional Products ltd, Switzerland) (group B1). Both diets were in mash form.
• the composition of the diets and the concentration of benzoic acid in the diet B1 are presented in the table 1.
• the basal diet A1 was formulated to meet the animals' requirements according to Henry et al. (1989, L'alimentation desumble domestiques - porc, lapin, volaille, 2nd edition, INRA, Par is) and NRC (1998), which publication is herein incorporated as reference.
• each group was divided into 2 equal groups of 16 animals each and were housed in floor-pen cages in sub-groups of 4 animals each in an environmentally controlled room for an observation period of 91 days.
• Each pen had a plastic-coated welded wire floor and was equipped with two water nipples and four stainless-steel individualised feeders. Room temperature was 21-22° C and humidity percentage was 50 %.
• Pigs ingesting during the post-weaning phase the diet without benzoic acid were fed the basal diet (group A2) or the A2 diet supplemented with 1 % of benzoic acid (group B2).
• Pigs fed during the post-weaning phase the diet supplemented with 0.5 % of benzoic acid received the A2 diet supplemented with 0.5 % of benzoic acid (group C2) or the A2 diet supplemented with 1 % of benzoic acid (group D2).
• the composition of the diets and the concentration of benzoic acid in the diets B2, C2 and D2 are presented in the table 2. All the diets were given in a mash form.
• the basal diet A2 was formulated to meet the animals' requirements according to Henry et al. (1989) and NRC (1998).
• the determination of the concentration of benzoic acid was performed according to a standard method.
• the collected bones were the right internal and external metacarpal. Samples were prepared from each of the collected bones immediately after slaughter. After careful removal of the soft tissue, a diaphysis section was obtained by sawing each bone. The obtained sections of about 3.5-cm long were immediately subjected to compression in order to determine the force in Newton necessary to break them (maximal-breaking force at the fracture point). The measurements were performed with a LR10K compression machine, using a XLC/10K/A1 force captor and a compression device TH23-196/AL (Lloyd Instruments, Fareham, UK). The broken bones were then dried in a drying oven at 105°C during 24 hours and the dry matter (DM) was used for the determination of ash content, which was measured after 48h incineration at 550°C in a muffle furnace.
• DM dry matter
• the animals did not present any symptoms of illness during the experiment. Furthermore, no natural mortality was observed and thus all the initial piglets were present during all the duration of the experiment.
• the bone resistance was significantly increased in all the supplemented groups (table 3).
• the mean resistance of the bones of the supplemented animals, groups B2, C2 and D2 represented respectively 128, 127 and 122 % of that of the controls.
• the ash content of the bones of the pigs ingesting supplements of benzoic acid was also increased (table 6).
• the ash content was significantly higher in the animals of the groups B2 and D2 than in the controls. That of the animals of the group C2 was numerically higher (P ⁇ 0.07) than that of the controls.
